  "textContent": "Provided are a positive electrode material, and a preparation method and a use thereof. The positive electrode material has a Dv50 value of α, with the unit of um, the lithium-rich amount of the positive electrode material is y, and the average porosity of the positive electrode material is denoted as β % in percentage, α, β, and γ satisfying: δ=β−[2α+75γ]/3, where 0≤δ≤4.0. By means of defining the relational expression of the Dv50, the average porosity and the lithium-rich amount of the positive electrode material, a lithium-ion battery prepared by the positive electrode material has excellent specific capacity, energy density, rate capability and cycle performance simultaneously, and particularly can maintain excellent electrochemical properties at high voltage.",
